Hello, I am attempting to use Sunbird 0.7 with Calendar Server trunk pulled from today's (1/18) source...I also tried it with last night's trunk, but it looks like nothing has been changed in a couple of weeks anyway. I was able to successfully connect and create a calendar with Sunbird. I'm running into this weird issue that is reproducible every time. When I try to go in and create an event before 1:00 P.M., and this is on Sunbird on a Mac or PC, I get the following error: 2008-01-18 20:16:55-0800 [-] [caldav-8009] [-] "'In transformToNative, unhandled exception: twistedcaldav.timezones.TimezoneException: Unknown time zone: /mozilla.org/20070129_1/America/Los_Angeles'" If I create an event 1:00 P.M. or later, it creates the event just fine. Also, when I move an existing event, back past the 1:00 P.M. mark (say 11:00 A.M.), it will allow the move of that event. Once I get an event in the A.M. I can create events at any time of day, even between restarts of the server. However, if I delete all of the events, restart the server, I have the timezone issue above. I suppose I have a work around, but it still is very weird. Anybody have any ideas? I am running Calendar Server on Tiger on a PPC.
